The Java Virtual Machine (JVM) is a key component of the Java architecture. It is an abstract computing machine that enables a computer to run a Java program, or any other program that has been compiled into Java byte code. The JVM is responsible for interpreting Java byte code and translating it into actions or operating system calls.

The Java Virtual Machine is platform-independent, meaning that it doesn’t matter what hardware or operating system the program is running on. You can write a Java program on one system and run it on any other system that has a JVM installed, be it Windows, Mac, Linux, or others. This universality of Java, largely credited to its JVM, is encapsulated in the tagline, “Write once, run anywhere.”

Apart from interpreting byte code, the JVM also provides a number of other functions, such as memory management, garbage collection, security, and threading, among others. It is crucial in the Java ecosystem and significantly contributes to the language’s popularity for building platform-independent applications.
